공업용 pH측정기 HP-480

개요

공업용 pH측정기 HP-480은 사용 빈도가 높은 기능을 중심으로 구성된 pH측정기 입니다. 각종 공업 분야에서 제조공정의 감시, 품질검사, 수산, 양식까지 폭넓은 용도로 사용됩니다.

기능

  • 간단한 교정 : 표준액에 pH전극을 담근 후, 표시되는 지시에 따라 ENT키를 눌러서 교정을 실행하는 간단한 자동교정
  •  전극의 상태 자동 판단 : 교정시 감도, 응답속도를 이용하여 자동적으로 pH전극의 상태를 판단
  •  5종류의 온도 보상 소자에 대응 : 500Ω, 6.8kΩ, 1kΩ, 10kΩ, 350Ω 5종류의 온도 소자에 대응
